BOILER-CLEANER.

I Specification of Letters Patent.

Application filed November 20, 1912.' Serial No. 732,526.

To all whom it may concern Be it known that I, ELZA H. REITER, a citizen of the United States, residing at Elgin, in the county of Kane, State of Illinois, have invented certain new and useful Improvements in Boiler-Cleaners; and I do hereby declare the following to'be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

The present invention relates to certain novel and useful improvements in boiler cleaners and has particular application to an apparatus of the class described by means of which scale, sediment, incrustation and like foreign matter may be removed from the boiler. 1*

In carrying out my invention it is my purpose to provide an apparatus by means of which all foreign matter may be removed from the boiler without the loss of the hot water usually wasted in blowing boilers down.

A further object of my invention is to provide an apparatus of the class described which is positive and continuous in its operation, so that a considerable saving of fuel, water and labor is attained, While at the same time the efficiency of the boiler is increased and a better circulation results.

' It is also my purpose to provide a boiler cleaning apparatus which will embody in its construction the desired features of simplicity, reliability, and economy in the cost of installation and operation.

IVith the above recited objects and others of a similar nature in View, my invention consists in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended claims.

In the accompanying drawings: Figure 1 is a view in side elevation of the preferred embodiment of my invention, certain of the parts being broken away. Fig. 2 is a top plan view. Fig. 3 is a vertical sectional View taken through the boiler.

In the present instance it is my purpose to provide, among other features, a tank connected with the blow off pipe of the boiler, a pump connected with the tank, and a connecting pipe leading from the pump back to the boiler so that a continuous circulation of the water is attained and during the course of circulation of the water any sediment, scale or other foreign substances contained therein Will be carried to the tank and settle therein so that the water returned to the boiler through the pump is comparatively free of impurities.

Referring now to the accompanying drawings in detail, the numeral 1 indicates a boiler of any approved character or type which is herein conventionally illustrated as a fire tube boiler.

The settling tank is indicated by the numeral 2 and is of any suitable form and dimensions, and preferably arranged at any point in relation to the boiler which may be convenient.

At 3, I have shown a pump of any approved type which will be found adapted for use in connection with this particular apparatus.

Located Within the boiler and beneath the tubes 4 is a flared chamber 5 for the collection of sediment, said chamber being open at the bottom and located above the blow-ofi' pipe 6 which communicates with the boiler at any suitable point. By this arrangement the flared chamber will collect the foreign substances and impurities and permit such to drop into the pipe 6, and at the same time, there is sufficient space between the pipe and chamber to let the water out of the boiler. This blow-off pipe is provided with a valve 7, the usual blow off pipe terminating at 8 and having the ordinary stop valve 9.

The numeral 10 designates a chamber adjacent the end of the blow off pipe in which the heavier particles of sediment or other foreign matter may settle, this chamber forming a three-way coupling for the pipe 6, the valve 9 of the blow-off and the pipe line 11 which is connected to the tank 2 at 12, the connection being preferably made at approximately the center of the tank.

Leading from the top of the tank 2 to the pump is a pipe 13 through which the water from the tank is drawn to the pump upon the suction stroke of the latter. A second pipe line 14 leads from the pump to the boiler preferably making its entrance into the boiler at the front thereof and discharging at its open end 15. The pipe connection 11 is provided with a stop valve 16, while the pipe 13 extending between the tank and the pump is also provided with a cut-off valve 17. Likewise, the pipe line 14 leading from the pump to the boiler is Patented Jan. 27, 1914.

provided with a valve 18 adjacent the pump and near its point of entrance to the boiler, this pipe 14 is'provided with a check valve 19 and a stop cock 20.

The numeral 21 indicates a blow-01f pipe for the tank and is provided with a valve 22, the tank being further provided with a clean out door or hand-hole 23.

From the above description taken in connection with the accompanying drawings, the construction and operation of the form of apparatus shown in Figs. 1 to 3 inclusive will be readily understood by those skilled in the art. The water from the boiler which is liable to contain sediment, floating scale and other foreign substances passes through the flared chamber 5 and from the boiler through the blow-0E pipe 6 to the coupling chamber 10, the valve 7 being open. Some of the heavier particles of sediment are liable to'settle in the chamber 10, the water flowing up through the pipe 11 past the Valve 16 to the tank 2. The tank is of such relatively large dimensions that the circulation therein is comparatively slow thereby allowing the sediment to settle at the bottom of the tank where it can be drawn ofl' through the blow-ofi' pipe 21 when the valve 22 is open. The pump being in operation the water is drawn from the tank through the suction pipe 13 to the pump and is then forced out through the discharge pipe 14 back into the boiler.

It will thus be observed that a continuous circulation of t e water is attained and in the travel of the water through the various parts of the apparatus, as described, the sediment and other foreign matter is collected so that on the return of the water to the boiler it is comparatively free from impurities.

, While I have herein shown and described one particular embodiment of my invention, I wish it to be understood that I do not limit myself to all the precise details of construction herein set forth by way of illustration, as modification and variation may be made without departing fromthe spirit of the invention or exceeding the scope of the appended claims.

What is claimed is:

1. The combination with a boiler, a settling tank and a pump, of a flared sediment collecting chamber located within the boiler, a valved discharge pipe leading from the boiler at a point directly below the sediment chamber to the tank, a settling chamber located in said discharge pipe, a valved blow off for said chamber, a'valved suction pipe leading from the tank to the pump, a return pipe leading from the pump to the boiler and throu h which the water is returned to the boiler, a plurality of valves for said return pipe and a valved drain pipe for the tank.

2. The combination with a boiler, a settling tank and a pump, of a combined coupling and settling chamber, a valved pipe connecting said chamber with the boiler, a second valved pipe connecting the chamber with the tank and a third valved pipe forming a blow ofi or drain for the chamber, a valved suction pipe leading from the tank to the pump and a valved return pipe leading from the pump to the boiler and through which the water is forced from the pump to the boiler.

In testimony whereof, I afiix my signature, in the presence of two witnesses.
